EYEGLASSES.

:EPEGIFICATIDN forming part of Letters Patent No. 743,679, datedNovember 10, 1903.

Application iisd J' uly 24,1903. Serial No. 166,785. (No model.)

To all whom it may concern:

Be it known that I, WALLACE. L. BEMrs,`of Brockton, in the county ofPlymouth and State of Massachusetts,have in vented certain new anduseful Improvements in Eyeglasses,

of which -the following, taken in connection with the accompanyingdrawings, is a specification.

My invention relates to eyeglasses, and especially to the stud andclamps by which and the nose-spring the two lenses are connectedtogether; and it consists in certain novel features of construction,arrangement, and combination of parts, which will be readily understoodby reference to the description of the accompanying drawings and to theclaims hereto appended and in which my invention is clearly pointed out.

Figure l of the drawings is an inside elevation of a pair of eyeglassesembodying my invention. Fig. 2 is a similar elevation of a portion ofone lens with the stud and clamp attached thereto. Fig. 3 is an edgeview of the same. Fig. 4 is a section on line A A on Figs.f2 and 3; andFig. 5 is a similar section, but showing a slightly-modified form of thestud. Figs. 2, 3, 4, and 5 are drawn to an enlarged scale.

In eyeglasses as heretofore constructed the studs to which thenose-guards and the nosespring are attached have projected toward eachother in a plane parallel to the' face of the lenses, therebynecessarily increasing the distance between the centers of the lenses,

which while it might be all right when used' with small lenses is foundto be objectionable when used with lenses having an increased area, asnow very generallydemanded, because of throwing'the centers ot thelenses too far apart; and the object of my invention is to obviate thisobjection, and to this end I construct the clamp and stud as illustratedin the accompanying drawings, in which l represents the lenses; 2, theclamp comprisingl two ears to embrace opposite sides ot' the lens andconnected together by the strap 3, which is curved to lit the curvededge of the lens in a Well-known manner.

The stud 4 projects from the ear of the clamp, which is in contact withthe rear face of the lens and at a right angle to said rear face ofthelens and is entirely within the ou ter edge of the strap 3, or, inother words, no parts of the two studs approach nearer to each otherthan do the straps 3. n

The stud 4 may have formed therein a vertical mortise or slot 5,entirely back of the rear face of the lens, wit-hin which are fitted andsecured by a suitable screw 6 one end of the nose-spring 7 and one endot the noseguard S, as shown in Fig. l.

Instead of the mortise or slot 5 extending transversely through thestud, as shown in Fig. 4, an open groove 9 may he cut vertically throughthe side of said stud, which coincides with the outer curved edge of thestrap 8, as shown in Fig. 5, and the ends 0i the spring and thenosefguard may be placed in said groove overlapping each other andsecured therein by a suitable' screw Without departing from theprinciples of my invention. By this construction of the stud theadjacent edges ofthe two lenses may be brought nearer to eachother thanwhen the studs project from the outer face of the straps 3 toward eachother in-a plane parallel to the face of the lens, as is now generallypracticed, which is a great advantage when applied to the lenses havinglargely-increased areas, which are now com ing into very general use.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. In an eyeglass the combination with a rimless lens, and a slottedclamp and a curved strap fitted to the inner edge ot said lens andclamped thereto, of a stud projecting from said clamp and strap to therear of the face of the lens and entirely within the outer edge of saidstrap or in such position relative thereto that no part of said studshall be at a less distance from the opposite lens than the outer edgeof said strap, and having formed therein a vertical slot to receive theends of the nose spring and guard the broad side of said slot being in aplane at a right angle to plane of the rear face of the lens.

2. In an eyeglass the combination with the lens, and a slotted clamp anda curved strap tted to the inner edge of said lens and firmly securedthereto, of a stud attached to and projecting from said clamp'and strapto the rear of the face of said lens and entirely within the outercurved edge of said strap, or in such position relative thereto that nopart of said stud shall be ab a less distance from the opposite lensthan the 0u ter edge ofsaid-strap,

said stud having@l mortse-like slot eutvtransversely therethrough withits narrowess edges 5 parallel to the face of the lens.
